Key Document


This reference design demonstrates a low-power boost converter solution used for door and windows sensors. The design includes an alkaline battery, an ultra-low quiescent-current boost converter and ultra-low power consuming digital Hall effect sensors. It can also power an ultra-low power, sub-1-GHz wireless microcontroller used to transmit the status of sensors.

  • Powered source from an alkaline battery
  • 300-nA ultra-Low IQ boost converter
  • Integrated LDO for noise sensitive load
  • Magnetic field sensing always powered on to enable continuous monitoring
